The year 2023 marks the diamond jubilee of the establishment of the Organisation of African Unity (OAU), currently known as the African Union (AU), which was founded in Addis Ababa. The visionary founders, including President Kwame Nkrumah and Emperor Haile Selassie, aimed to bring about political change in African states and restore the dignity of African people, who had long suffered under colonial subjugation and disenfranchisement. Their vision encompassed a united Africa, free from oppression, governed by self-determination, and destined for prosperity.

Over time, the OAU transformed into the AU, with the intention of accelerating the dream of African unity and eradicating the social, political, and economic challenges that had begun to define African states. Pan-Africanism emerged as a beacon of hope, inspiring many who understood its significance at the organisation's inception. As we reflect on the ideals cherished by the founding fathers and reaffirmed by their successors in 2002, it is crucial to contemplate four of the seventeen aims articulated during the launch of the African Union in Durban.

Unity and solidarity between African countries and their people

Firstly, the AU aims to achieve greater unity and solidarity between African countries and their people. In pursuit of this goal, notable actions have been taken, such as the establishment of the Peace and Security Council (PSC) to maintain peace in conflict zones such as Mali, Sudan, Somalia, and the Central African Republic. Moreover, in response to the COVID-19 pandemic, the AU set up the Africa Medical Supplies Platform (AMSP) to facilitate the procurement and distribution of medical equipment and supplies throughout the continent. While these achievements are commendable, the majority of the other intentions under this aim lack a concrete plan of action, and the lack of sufficient funding is hampering progress. This presents a cause for concern.

Secondly, the AU pledged to defend the sovereignty, territorial integrity, and independence of its member states. Despite the development of intervention instruments to support this aim, the organisation has been found wanting at critical junctures. One cannot forget the adoption of Resolution 1973 by the United Nations Security Council, which authorised national governments or regional organisations to impose a no-fly zone in Libya, ultimately leading to the assassination of Colonel Muammar Gaddafi. Colonel Gadhafi played a pivotal role in the formation of the African Union and declared his vision for the United States of Africa with a single government and one currency. Surprisingly, three AU member states – South Africa, Nigeria, and Gabon – voted in favour of this resolution. Their actions raised doubts about their commitment to defending the sovereignty, territorial integrity, and independence of the AU.

Africa faces a harsh reality

Africa, a continent with immense potential for growth and development, faces a harsh reality that cannot be ignored. Its burgeoning population holds great promise for contributing significantly to its advancement. Additionally, Africa is blessed with abundant mineral resources, the prudent management of which could sustain the developmental aspirations of its people. Furthermore, Africa's expansive land mass and diverse climate present valuable opportunities to address crucial concerns such as food and energy security. It is perplexing that Africa, a continent three times the size of the United States of America, continues to lag behind in all aspects of development. The continent has enormous potential to foster growth and development and to compete on a global scale. Regrettably, it has thus far failed to harness this potential, leaving the dream of African prosperity, initially envisioned by the founders of the OAU (AU) and their successors, frustratingly out of reach.

As we commemorate the diamond jubilee of the OAU's establishment, let it serve as a reminder of the vision and determination of its founders. Their dreams for an Africa united, free from oppression, and governed by self-determination still resonate today. It is our collective responsibility to ensure that these dreams are no longer scuppered, but rather transformed into a vibrant reality of African prosperity.

NRF grants of millions for Kovsie professors

Two professors received research grants from the National Research Foundation (NRF). The money will be used for the purchase of equipment to add more value to their research and take the university further in specific research fields.

Prof Martin Ntwaeaborwa from the Department of Physics has received a R10 million award, following a successful application to the National Nanotechnology Equipment Programme (NNEP) of the NRF for a high-resolution field emission scanning electron microscope (SEM) with integrated cathodoluminescence (CL) and energy dispersive X-ray spectrometers (EDS).

Prof Bennie Viljoen from the Department of Microbial, Biochemical and Food Biotechnology has also been awarded R1,171 million, following a successful application to the Research Infrastructure Support Programme (RISP) for the purchase of a LECO CHN628 Series Elemental Analyser with a Sulphur add-on module.

Prof Ntwaeaborwa says the SEM-CL-EDS’ state-of-the art equipment combines three different techniques in one and it is capable of analysing a variety of materials ranging from bulk to individual nanoparticles. This combination is the first of its kind in Africa. This equipment is specifically designed for nanotechnology and can analyse particles as small as 5nm in diameter, a scale which the old tungsten SEM at the Centre of Microscopy cannot achieve.

The equipment will be used to simultaneously analyse the shapes and sizes of submicron particles, chemical composition and cathodoluminescence properties of materials. The SEM-CL-EDS is a multi-user facility and it will be used for multi- and interdisciplinary research involving physics, chemistry, materials science, life sciences and geological sciences. It will be housed at the Centre of Microscopy.
“I have no doubt that this equipment is going to give our university a great leap forward in research in the fields of electron microscopy and cathodoluminescence,” Prof Ntwaeaborwa said.

Prof Viljoen says the analyser is used to determine nitrogen, carbon/nitrogen, and carbon/hydrogen/nitrogen in organic matrices. The instrument utilises a combustion technique and provides a result within 4,5 minutes for all the elements being determined. In addition to the above, the machine also offers a sulphur add-on module which provides sulphur analysis for any element combination. The CHN 628 S module is specifically designed to determine the sulphur content in a wide variety of organic materials such as coal and fuel oils, as well as some inorganic materials such as soil, cement and limestone.

The necessity of environmental protection has stimulated the development of various methods, allowing the determination of different pollutants in the natural environment, including methods for determining inorganic nitrogen ions, carbon and sulphur. Many of the methods used so far have proven insufficiently sensitive, selective or inaccurate. The availability of the LECO analyser in a research programme on environmental pollution/ food security will facilitate accurate and rapid quantification of these elements. Ions in water, waste water, air, food products and other complex matrix samples have become a major problem and studies are showing that these pollutants are likely to cause severe declines in native plant communities and eventually food security.

“With the addition of the analyser, we will be able to identify these polluted areas, including air, water and land pollution, in an attempt to enhance food security,” Viljoen said. “Excess levels of nitrogen and phosphorous wreaking havoc on human health and food security, will be investigated.”
